This is a fun map and quite challenging.
It's a small garden area with two fortresses. You're starting in your home base and your goal is, to enter the second base. Before the target opens, you need to press a switch several times, and every time you press this switch, you're given new ammo and a crowd of monsters is spawned outside. The monsters are getting harder with every wave.
There's no exploration in this map, but it's a very entertaining prove of skill. 4/5 -Milian
